SWIVEL-CONNECTION FOR VALVES AND THEIR SPINDLES.

SPECIFICATION forming part of Letters Patent No. 324,676, dated August18, 1885.

Application filed March 16, 1985.

(N model.)

To all whom, it may concern Be it known that I, HENRY R. FRISBIE, acitizen of the United States, residing at Cromwell, in the county ofMiddlesex and State of Connecticut, have invented new and usefulImprovements in Swivel-Connections for Valves and Spindles, of which thefollowing is a speciiication.

This invention relates to improvements in 1Q swivel-connections forvalves and their spindles, the object being to provide improved meansfor connecting valves to their spindles in globe-valves, stop-cocks, andother similararticles, whereby the valve is permitted to I 5 turn on theend of the spindle, or the spindle to turn in its valveconnection, afterthe valve becomes seated, and whereby the construction of suchconnections is much strengthened and simplified, and the valve and thespindle are disconnected one from the other with great facility.

In the drawings forming part of this specification, Figure 1 is avertical section of a globe-valve having its spindle and valve con- 2nected by devices embodying my invention. Fig. 2 illustrates in detailin perspective the lower end of the valve-spindle, the valve, apacking-ring, and a screw whose use is hereinafter described. Fig. 3 isa perspective view 0 of the valve.

In the drawings, A is the body of the globevalve, having the usual seat,10, therein and provided with the hub B, in which the spindle c issupported, and is turned to move it 5 up and down by means of thescrew-thread connection it has with the hub B.

The spindle c has an annular groove formed therein near its lower end,whereby is made the laterally projecting collar 0 below said 40 groove.and the lower end of the spindle has a hole in it, as shown. In spindlesno larger above the collar 0 than the part adjoining it the collar onlywould engage under the lip 12 with the valve.

The valve (Z has a hole, 122, centrally through it, which is providedwith a screw-thread corresponding to that on the screw 2, the latterbeing adapted to screw into the valve (1, and its plain unscrewed endabove its screwed part to project above the upper face of the valve, asshown.

On the upper side of valve (2 is formed a spindle-socket adapted toreceive the lower end of the spindle 0 and the collar c on the latter.The spindle-socket referred to consists of a wall standing at rightangles to the face of the valve, on the upper side thereof, of a heightabout equal to the thickness of the collar 6 on the spindle, the mainportion of said Wall being concentric with the center of the hole at inthe valve, but having an opening on one side, as shown, and said wall issurmounted by an inwardly-projecting lip, 12, of a thickness about equalto the groove in the spindle above collar 0, whereby thereis formed asocket, 0, around under said lip, adapted to receive the collar 0, whilethe lip itself enters the groove above the latter.

The spindle in Fig. 1 is attached to the valve by passing its collaredend through the side opening in said socket to a central position overthe hole m, and then securing it there by the screw 2, as shown, theplain end of the latter entering the hole in the end of the spindle.Thus the valve is perfectly free to turn on the spindle, but is firmlylocked thereon.

In certain valve constructions it is desirable to provide the side ofthe valve which is forced against the seat w with a packing-ring ofrubber or similar yielding material or of lead or simi 8o lar softmetal, and where such a ring is required the face of the valve has agroove, 2', to receive the packing-ring w, and the latter is held thereby the screw .2, whose head engages with the inner border of said ring,as shown in Fig. 1.

The above-described valveand ring. arrangement facilitates the replacingof worn or burned out packing-rings with new ones.

The above-described improved stern and valve-eonnection is a very strongone, and can be made very economically in comparison with other meansheretofore employed, for the valve can be cast with its spindle-socketsubstantially ready for receiving the end of the spindle, and for largevalves the latter also may be cast suf- 9 5 ficiently perfect to admitof their being applied to the valves 'without finishing.

What I claim as my invention is A swivel-connection for a valve andspingaging with the valve and having its plain (lle, consisting of aspindle-socket on the valve end entering the lower end of the spindle,comhaving an opening at one side substantiallybinedandoperatingsubstantiallyasdescribed. 10 as described, said sockethaving an inwardly- HENRY R.
